Choosing between Daly and Pinzhiyuan: Select based on process (Daly offers potting for waterproofing/shock resistance), series count (Pinzhiyuan: 3–35S; Daly: 3–24S), current (Pinzhiyuan: 5–450A; Daly: 15–200A), and specific needs (Daly for motive power; Pinzhiyuan for all-scenario applications).
III.
Jikong & Jiabaida
Battery protection board manufacturer recommendations? Jikong and Jiabaida (popularized via Douyin/TikTok DIY lithium battery content).
Jiabaida—Features passive balancing only. Advantages: An established brand with wider recognition than Jikong;
suitable for automated production lines (favored by large companies for CCS-style automated manufacturing); supports inverters with communication protocols (though standard motive power boards do not). Disadvantages: Notorious for having the worst after-sales service in the BMS industry; repair times exceeding a month are common, and customers often have to shoulder the burden of after-sales issues themselves.
Jikong (JK) — Features active balancing that transfers energy from high-voltage cells to low-voltage cells; ideal when energy deviation exceeds 5W. Pros: Best after-sales service (one-year warranty, with free repairs or even replacements after the warranty expires); high-quality power boards (failure rate of only 7 out of 1,000 units); supports a wider range of inverter protocols than Jiabaida. Cons: State-of-Charge (SOC) estimation deviation exceeds 5%; requires recalibration via a full charge or full discharge every two to three months.
Choosing between Jikong and Jiabaida: Select based on balancing method (Jikong: active balancing; Jiabaida: passive balancing), application (Jikong: energy storage; Jiabaida: automated production lines/CCS), after-sales service (Jikong: best; Jiabaida: worst), or specific needs (Jikong: energy storage; Jiabaida: automation).
